Abstract

Способ удаления летучих жидких загрязняющих веществ из загрязненного объема земли, причем этот загрязненный объем залегает выше незагрязненного слоя земли, причем этот способ содержит этап нагрева незагрязненного слоя до тех пор, пока температура существенной части незагрязненного слоя, который прилегает к загрязненному слою, достигнет, по меньшей мере, температуры точки кипения загрязненных жидкостей с тем, чтобы предотвратить движение парообразных загрязняющих веществ по направлению вниз из загрязненного слоя земли.Международная заявка была опубликована вместе с отчетом о международном поиске.A method for removing volatile liquid contaminants from a contaminated earth volume, this contaminated volume being above the uncontaminated earth layer, this method comprising the step of heating the uncontaminated layer until the temperature of a substantial portion of the uncontaminated layer that is adjacent to the contaminated layer reaches at least boiling point of contaminated liquids in order to prevent the vaporous downward movement of pollutants from the contaminated layer of the earth. The application was published with the international search report.
